Patented July 1, 1930 UNITED STATES PATENT OFFICE ROBERT EONSCH, OF UNION CITY, NEW JERSEY, ASSIGNOR TO DUPLEX SAFETY WINDOW CORPORATION, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF DELAWARE WINDOW CASING Application filed January 26, 1929. Serial No. 335,167. I

This invention relates to sashes and frames for conventional types of windows, and more particularly to double hung windows in which two sashes are independently slidable between vertical frame members.

The present demands in such structures 1nclude weather proofing devices capable of excluding moisture and wind effectively, and, on the other hand provide means for adequate 1o ventilation when required.

It is also desirable that either sash may be raised and lowered easily and smoothly without binding or appreciable wear or corrosion of the parts in frictional contact.

It is further regarded as highly advantageous to arrange that portion of the sash containing the glazing in such manner as to pivot inwardly, thus presenting both sides of the pane for the purpose of cleansing, avoiding the usual hazards and inconvenience encountered in such operations, the sash being automatically locked when in an upright position.

These andmany other importantand desirable features, which will become evident as the description progresses, are accomplished by the novel and practical construction, arrangement and combination of parts as hereinafter described andillustrated in the accompanying drawings, constituting a material portion of this disclosure, and in which Figure 1 is a sectional perspective view of a double hung window as made in accordance with the invention.

Figure 2 is a sectional view taken in a vertical plane indicated by the line 22 of Figure 1.

Figure 3 is a perspective View, drawn to a smaller scale, of the metal parts of one side of the window sash.

Figure 4 is a transverse sectional view of the sashes and frame at one side of a window, showing one form of construction.

Figure 5 is an enlarged fragmentary side elevational view of the sash braces shown in an inclined, operative position.

Figure 6 is a transverse sectional view taken on line 66 of Figure 5.

60 Figure 7 is a sectional view, similar to Figure 4, but showing a modified form of construction.

Figure 8 is another like sectional view of a further modification of construction.

It is to be noted that the drawings show the window frame stiles, designated by the numeral 10, as flat, level and unbroken by rabbeting or grooving at their inner surfaces to receive parting strips, therefore being stronger and less expensive to produce than usual.

These stiles connect between a lintel, not shown, and sill 11 in the ordinary manner. Secured to the adjacent sides of the stiles are plain rectangular. outer retaining strips 12 and at the front are moulded inner retaining strips 13, intermediate of which are parting strips, generally designated by the numeral 14, and which will be described in detail later on.

The sashes 15 and 15, respectively inner and outer, contain glass panes 16 and 16' held in the usual manner as indicated, and it will be seen that the inner sash 15 is wider than the outer sash 15, so that the outer sash, as will be shown later, may be swung between the lower stiles 38, and their protruding parts 42, thus permitting the cleaning of the upper glass also from the interior while standing on the floor. 80

Both sashes contain recesses 17 midway in the length of their side members, see Figure 2, and at their upper corners are angular recesses 18; other transverse recesses 19 are formed in their bottoms to extend in from each side.

Fixed to the outer edges of the sashes are metal plates 2020' having in reaching right angular elements 21 provided with upstanding members 22 extending into the recesses 19.

The central portions of the plates 20 are offset inwardly, as at 23, to extend into the recesses 17, the offset portions 23 containing longitudinal slots 24 in the inner edge of which are a series of notches 89 their purpose becoming later apparent.

A metal chain holder strip 26 is fixed on the upper portion on the outer side of the plate 38, the lower end of the strip terminatin in a prong 27 to engage a loop 28 at the en of- 100 a sash cord or chain 29, arranged in the usual through registering openings 88 in the plates 20 and 38 and strip 26.

The parting strip 14, as seen in Figures 1 and 4, is formed of sheet metal to produce a rectangular inreaching member having a straight flat outer face 33, right angular sides 3434 creased inwardly at both sides to constitute channels 35-35, and then flanged outwardly at 3636', these flanges being firmly held against the frame stile 10 by screws 37 passing centrally through the face 33.

An integral inner sash guide member is formed of sheet metal to present a face 38 arrangedclosely' adjacent the plate 20, one edge of the guide being bent at a right angle 39 to contact the side of the inner retaining strip 13 and provided with a flange 40 to contact the stile 10, the guide face 38 being in the plane of the strips 13 and 14.

The opposite side edge of the guide 38 is extended outwardly to form a loop 41 loosely engaging over the extending edge of the plate 30, presenting a weather obstructing joint, then folded tightly re-entrantly upon itself as at 42, the outer surface of the doubled loop being in register with the outer surface of the parting strip 14, a continuation of the loop making contact with the face 33 of the strip, thence to be turned at a right angle at 43 to engagethe front side 34 of the strip and terminate in an'outturned flange 44 engaged in the front channel 35 of the parting strip as best seen in Figure 4, providing an effective weather proof joint.

The outer sash guide presents a face 45, its front edge being bent to form an angular member 46 making contact with the rear side 34' of the parting strip 14 and having an outturned flange 47 to interengage in the rear channel 35 of the parting strip.

The opposite, outer edge of the guide is continued outwardly to form a loop 48 loosely engaging over the extending edge of the plate 20, the material being turned closely reentrantly upon itself, as at 49, so that the outer surface of the doubled loop contacts with the face of the outer retaining strip 12, thereafter being bent, at a right angle, as at 50, to contact the forward surface of the strip and terminating in a flange 51 contacting the stile 10.

From the foregoing it will be seen that the guides are inter-engaged by the parting strip 14 by metal surfaces and held against the stile with suflicient tension to move smoothly, the shape of the flattened loops preventing the entrance of wind and rain.

Furthermore that the guide rails for the sash slides, which are only one for either sash, namely 34 and 34' respectively, run in rather shallow grooves, entirely hidden from atmospheric influences and dust, and for these combined reasons will neither jam nor corrode or stick. i

The doubling up of the sheet metal on the channels in which the sash plates 20 and 21 repose, makes these parts of the stiles extrastrong, guarding against collapse and resultant jamming, while the peculiar shape effectively excludes any access of moisture or dust to the inolosed contacting strip.

In the modification shown in Figure 7 the same general structure is employed, but the parting strip 14 is shaped to avoid the channels 3535', the side walls 55 of the strip extending straight to the stile 10 where they are outturned and bent re-entrantly, as at 56, to enclose the corresponding flanged edges of the sash guide elements, this form being less difiicult to construct and equally effective in the results attained.

The further modification disclosed in Figure 8, shows a parting strip formed to presentprojecting double angular guide elements extending the full length on both sides of the strip and the contacting elements of the sash guides 6667 are correspondingly formed to engage thereover, thus constituting a practical embodiment of the device.

Fixed on the side of the elements 38 of the sash guides, near their lower ends, are strip brackets 80 in which are secured bars 81 passing freely through openings in the guides and plates 20, into the recesses 19, the inner ends of the bars being journalled in the members 22, thus providing means for folding the sashes inwardly at will.

In order to support the sashes when in an inclined osition an arm 82 is pivoted on the sash gui es 38, as at 83, the reduced, free end 84 of the arm extending outward for convenience in operation.

Fixed in the arm, near its outer end, is a stud 85 passing freely in the slot 24 of the sash plate element .23 and adjustably receivable in any of the notches 25 of the slot.

Carried at the outer end of the stud 85 is a fixed washer 86, maintaining the arm in close but movable relation to the plate, and fixed in a slot in the washer 86 is a bent flat spring 87, its ends pressing against the edge of the slot, opposite the notches to urge the stud into engagement therewith, thus constituting an effective device for holding the sash at any desired inclination, providing for ventilation and permitting the sashes to be turned inwardly at an angle up to 90 degrees.

A little consideration will show that, when only, and to release it, either to close the window or to bring the stud further down into a deeper notch, the extension. 84 of the lever arm must be pressed down momentarily to disengage the stud and hold the spring compressed while tilting the sash.

At the upper portion of the guides 38 and 45 are slots 88 receptive of the latch pin 32 when the sash is in an upright position, positively locking it against movement relative to the sash, the pin being slightly tapered ofi at the end, as indicated, so as to automatically snap into engagement with the slot and to be retracted by pressing the spring 30-31 inwardly.

The device is so designed and constructed as to permit the outer sash to swing inwardly whether it is kept above or lowered while the inner sash is raised above it, thus enabling ready washing of the window conveniently and safely; ventilation maybe secured without draught by slightly inclining either sash. The construction is adapted to wear indefinitely and prevent rattling, as well as anyentrance of stormwater or wind.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention,

of which obviously an embodiment may be constructed including many modifications without departing from the general scope herein indicated and denoted in the appended claims.
